From: "Luis R. Rodriguez" <mcgrof@suse.com>
Its reported that mptsas can at times take over 30 seconds to recognize SCSI storage devices [0], this is done on the driver's probe path. Use the the new module_long_probe_init() to annotate this driver's probe is broken and require some love, but makes the driver operational until that is fixed.
